Hello guys, need help to diagnose the car making squeal noise in the morning then it's gone when it's getting warm like after 3 to 5 minutes.
Thanks.

Hi,

This model wasn't offered in the US until 2014, so my technical information is very limited. I can tell you that what you described sounds like a loose belt. When the vehicle is first started, that is when the most load is placed on the alternator. If the belt is loose or worn, it will squeal.

With the engine off, check to make sure it is tight. If it is, try this. Start the engine. While it is making the noise, pour a small amount of water on the belt. If it chances pitch, sound, or even stops, replace the belt and them make sure it is properly tightened.

I did attach a picture of the belt on a 2014. I circled the alternator. I don't know if yours will be the exact same.

If you try the water trick, the engine will be running, so protect your eyes and clothing. Water and dirt can fling off the belt.

Let me know what you find.

I can see the belt running not straight. So I am going to do exactly what you said.

I went to a mechanic and he said there is nothing wrong with it the belt is fine.
And here is the pictures of the belt.
I can make a video if it's needed.

Did you try the water trick to confirm the belt is tight enough. And yes, from the pics the belt looks good. Also, is it possible for you to record the sound when you hear it using your phone and upload it for me to hear?

One last thing. When it is making the noise, turn all electrical components on to see if it gets worse or off to see if it lessens. If I could hear it, I will most likely be able to tell you if it is a belt noise. I suspect it is, but can't confirm without hearing it. If you really wanted to, you could remove the belt and see if the noise is gone when you start it. However, only allow the vehicle to run a few seconds to confirm and then turn it off.

Let me know.
